Hi there!
The formula for the area of a circle is A = pi x r^2. Using this formula, we can plug in the radius and solve for the area.
WORK:
A = pi x (5)^2
A = pi x 25
A = 25pi cm^2
ANSWER:
B - 25pi cm^2
Hope this helps!! :)
If there's anything else that I can help you with, please let me know!
Answer:
∠1 = 51° ∠2 = 39°
Step-by-step explanation:
ok since the picture is a right angle put it equal to 90
like this:
3x + x + 22 =90
4x + 22 = 90
4x = 68
x = 17
now we plug it in:
3(17)= 51°
(17) + 22 = 39°
*a straight line is equal to 180, a right angle is 90
does that make sense?
